Heart rate variability as a biobehavioral marker of diverse psychopathologies: A review and argument for an "ideal range".

Heart rate variability (HRV), a measure of the variability in intervals between subsequent heart beats, is now widely considered an index of emotion regulatory capacity and the ability to adapt flexibly to changing environmental demands. Abnormalities in HRV are implicated in a host of psychopathologies, making it a potentially powerful transdiagnostic biobehavioral change mechanism in treatment interventions. While most mental illnesses are associated with low HRV, eating disorders have been linked to elevated HRV.

Confirmatory factor analysis of the EDE-Q in vegans and omnivores: Support for the brief three factor model.

The factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q) has proven difficult to replicate, including in vegans, whose eating behaviors differ from omnivores in important ways. We sought to assess fit of data from vegans and omnivores with the most recently proposed brief three-factor model of the EDE-Q, which retains only seven of the original 28 EDE-Q items. We examined fit indices of the EDE-Q brief three-factor model in vegans (i.

Practitioners' perspectives on ethical issues within the treatment of eating disorders: Results from a concept mapping study.

Objective: Treating patients with eating disorders (EDs) is associated with an array of ethical concerns, including balancing patients' health and autonomy, access to care, and use of harm-reduction versus recovery-oriented treatment models. The primary aim of the current study is to gain a better understanding of ethical issues faced by ED practitioners by using a concept mapping, or Q-sort, approach.

Method: A total of 12 practitioners completed the brainstorming phase and generated statements regarding ethical issues they faced while treating patients with EDs.

Factor structure of the Eating Disorder Examination - Questionnaire among heterosexual and sexual minority males.

Eating disorder (ED) pathology is increasingly recognized among males; however, presentations within males differ from traditional descriptions of ED pathology in females. Additionally, experiences of ED pathology differ between sexual minority (SM) and heterosexual males. These differences suggest that existing ED assessments, which are primarily based on female samples, do not adequately capture ED pathology in SM and heterosexual males.

Rapid response is predictive of treatment outcomes in a transdiagnostic intensive outpatient eating disorder sample: a replication of prior research in a real-world setting.

Objective: There is a growing call to identify specific outcome predictors in real-world eating disorder (ED) treatment settings. Studies have implicated several ED treatment outcome predictors [rapid response (RR), weight suppression, illness duration, ED diagnosis, and psychiatric comorbidity] in inpatient settings or randomized controlled trials of individual outpatient therapy. However, research has not yet examined outcome predictors in intensive outpatient programs (IOP).
